Abstract
Temperature and pH responsive semi-interpenetrating network (semi-IPN) hydrogel-based bilayer actuators were fabricated by generating a poly(N-isopropylacrylamide) (pNIPAm)-based hydrogel in the presence of positively charged polyelectrolyte poly(diallyldimethylammonium chloride) (pDADMAC) on a layer of gold-coated polydimethylsiloxane (PDMS). The bilayers showed unique bidirectional bending behavior in response to solution temperature and pH, which is a result of the modulation of the hydrogel solvation state in response to solution temperature and pH changes. The behavior described here is vastly different than what is observed from bilayers composed of just pNIPAm. The direction and degree of bending of the device could be easily adjusted by tuning the composition of the hydrogel layer. We also showed that the bilayers could be used as stimulus-induced grippers and for controlled/triggered small molecule delivery, which can make the bilayers useful for various biomedical applications.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
